Angular vs React: 6 Factors for In-Depth Comparison

Angular or React? React and Angular are both popular and robust JavaScript libraries and frameworks, respectively. Both resources can create magic in building an interactive and trendy front of the web app. Similarly, both can build complex front ends too. Then what's the difference between these famous JS resources? Let's look at the detailed comparison of Angular vs React to know what makes them different.

There are many comparable features of Angular and React. Both are efficient in creating a project with multiple features and different requirements. However, we will discuss factors like performance, testing, data binding, etc. Depending on these factors, we can differentiate between these two.

Along with that, we will see the pros, cons, and also features of both platforms, and then you will decide which one to choose for your next project. So, let's begin then!

What is Angular?

A Google team created Angular, a platform based on TypeScript that is open-source and known for web application development. If you would like to develop apps for mobile and web both, Angular is the framework to use.

Two-way data-binding is a feature that Angular offers above other technologies. It signifies that if you alter a value in the input field, the new property value of the component will be automatically generated. It will produce a faultless, real-time data synchronization between the model and the view.

You may be aware of this situation, but it is important to state it again to benefit inexperienced developers who might confuse Angular with AngularJS for about the same concept.

The main distinction between Angular and AngularJS is that even the former's primary language is TypeScript, which is a superscript for Js, and the latter is JavaScript. In reality, Angular resembles AngularJS more than anything else. 

What is React?

React was first made available and supported by Facebook as an open-source JS framework in 2013. It has made it possible to create single-page web apps (ReactJS) and mobile apps (React Native). 

React is a toolkit for creating interactive UIs inside its official paperwork. This JS library promotes repeatable UI components, enabling current data to change constantly throughout time without using much memory.

By utilizing a virtual DOM, React is frequently used by programmers to build front ends with improved performance.

Additionally, it can enable native cross-platform mobile apps with React Native as a basis and is successfully produced on the server utilizing NodeJS. 

Benefits and Drawbacks of Angular


Using Angular has several benefits, some of which are listed below:

  • There is a clean & tidy Code development option.
  • Improved Interface with Material Design Inspiring
  • Routing can also be handled by an angular framework, making shifting between views straightforward.
  • Updates with Seamless Angular Command Line Interface (CLI)


The foregoing are some drawbacks and problems with Angular:

  • An angular aspect may be confusing to beginners.
  • There isn't a detailed instruction manual or exhaustive, all-inclusive paperwork.
  • There is a significant learning curve.
  • Debugging scopes is tough due to the Limited Routing.
  • Angular can lag when pages feature interactive elements.
  • Collaboration with outside parties is challenging.
  • When updating from older versions to newer versions, several issues could occur.

Benefits and Drawbacks of React


Using React has several benefits, some of which are listed below:

  • The HTML-like language makes extensive documentation and scripting possible.
  • React is easy to learn due to its uncomplicated design.
  • Developers can focus more on building modern JavaScript and stress less about structure-specific code.
  • More reliable platform as it can create content-focused apps by improving server-side processing capability.
  • You can switch between versions of React. A large portion of the procedure is automated using a tool on Facebook called "codemod."
  • Native development can benefit from React development abilities.


The following are some disadvantages and problems associated with utilizing React:

  • It takes a lot of preparation to integrate Reacts with an ordinary MVC architecture like Rail.
  • A solid understanding of how to combine a UI with the MVC pattern is required for users of ReactJS.

6 facts of Comparison of Angular vs React

Let's begin with facts that make Angular and React similar, following with the differentiating factors:

1# Similarities

  • Both are available as open source. Due to the huge development communities for React and Angular, the materials are frequently improved.
  • Structure: Component-based structure is a feature of both Reactjs and Angular. These parts are eternally recyclable since they can be used inside other parts.
  • Both technologies are widely used by developers to create single-page apps (SPAs).
  • Simple updating: Both Angular and React provide simple updating. React is dependent on third-party libraries, whereas Angular leverages CLI. 
  • Performance-wise, Angular and React are comparable. The user's perspective mainly determines the difference.
  • Development platform: Both are utilized to create the frontend of a smartphone or online app

2# Features of React and Angular


Cross-platform features: React's subsidiary framework, named React Native, designed for creating cross-platform mobile applications, is another unexpected result of the technology. Additionally, it develops specialized mobile applications using React.js. 

Reusable components are offered by the component-based architecture of React.

All of your Reactjs components can be reused for this code reuse in other aspects of the program.

Clear abstraction: React spares the user from its intricate internal workings. 

The Declarative User Interface of the App is built using HTML by React technology.

Java is more complex and heavier than HTML. As a result, the workflow is not disrupted, and Angular can decide how the programming should flow instead of you having to prepare it ahead of time.


Angular CLI: The best Angular capabilities that programmers appreciate is the Angular CLI. By using App startup and app setup, the entire development system is operated.

Additionally, it supports LiveReload and allows you to preview the app.

Support for Ajax: Angular comes with built-in functionality for HTTP and Ajax, enabling connections and communication between clients and the server while enhancing performance. Ajax also speeds up response times for requests coming from both sides.

Angular also provides the best simplicity of maintenance. Completely separated components can be replaced with better ones to produce clean, maintainable code and upgrades.

Improved accessibility is also a feature of this framework. The majority of new engineers quickly get used to reading Angular code. Additionally, the developers' ability to engage with the platform is greatly facilitated by its readability.

3# Testing

React uses Jest in most cases for testing React projects. At the same time, Angular uses Jasmine mostly for testing purposes.

4# Popularity of React vs Angular

According to Stackoverflow overview of best web frameworks 2022 (up to June), out of 58,743 respondents, 42.62% choose ReactJS, and 20.39% choose Angular.

This huge difference is seen as Angular is not easier to learn like React. Hence, beginners, along with experienced developers, prefer React more than Angular.

5# Performance

As was previously said, a site's DOM poses the biggest obstacle to speed when using a JS framework or module (virtual or actual).

Possible performance concerns arise from Angular's using a Regular DOM, especially when many Ui components and web page data are present.

In summary, due to more effective state change and Virtual Tree updates, React's Virtual DOM is recognized as being considerably quicker than Angular's Normal DOM. 

6# Data Binding

Angular follows 2-way data binding, and React follows 1-way data binding, which is bi-directional and unidirectional, respectively.

In Angular, if the UI element is updated, the respected model also updates automatically, and vice versa. In comparison, this doesn't happen in React. Hence, it becomes easier to maintain React's data binding method than Angular's data binding method.

Final Verdict

On a simple note, no matter how you compare Angular vs React, there's no end to it. The concern is the requirement of your app. Depending on the type and complexity of the app, you can select any one JS platform for your upcoming project.
